Received: 04 October 2022; Accepted: 11 January 2023;Published: 02 February 2023. Impaired cytotoxic CD8(+) T cell response in elderly COVID-19 patients. This result indicates that CD4+ cytotoxic T cells play a major role in the S-specific cell-mediated cytotoxic response following BNT162b2 immunization. Based on phenotypic markers, T cell subsets can be classified into four subsets: nave (CCR7+CD45RA+), central memory (CCR7+CD45RA), effector memory (CCR7CD45RA), and terminally differentiated memory (CCR7CD45RA+). On the other hand, immuno-senescence associated with defects in immune proliferation and effector functions has been shown to correlate with an increased susceptibility to viral infection and a decreased vaccine immunogenicity (76). Close Compass for Simple Western and shut down Jess's computer. Overview of anti-SARS-CoV-2 immune response six months after BNT162b2 mRNA vaccine. CD4+ TCM resides within the lymphoid organs and are known for their rapid proliferation and production of IL-2 and IL-10 upon restimulation (66).
